A brief analysis of the differences between Fast_forword and srroll in SQL Server

WHEREId= @ID FETCH NEXT fromCr_cursor into @ID,@Name ENDCLOSECr_cursordeallocateCr_cursorThen we look at the execution plan, which is no different from the normal instant query, so I guess that if the data changes during cursor reading, it can be obtained. Let me verify this.DELETE from dbo. Employee WHERE ID = 252, and then in the read cursor to open one-step debugging, read the ID = 24 node3, and then before I read the next cursor

Slime: Database management phpmyadmin password-free configuration

the next phpmyadmin, password-free login access. Here we take app_db this database as an example. To implement password-free login, we also need to create a read-only user ilanniread in the MySQL database for the app_db database. Create the SQL statement as follows: Mysql-hrm-bp183j9f186nd4933.mysql.rds.aliyuncs.com-uroot-p ' Ilanni '-e "Grant Select on app_db.* to ' ilanniread ' @ '% ' ID Entified by ' readonlyqwe '; Once Ilanniread is created, we will now modify the phpMyAdmin configuration f

and is not transmitted over the network. Asymmetric algorithms are more costly and slow than symmetric algorithms. Therefore, we do not want to encrypt all information using asymmetric algorithms in online conversations. Instead, we use symmetric algorithms. In the following example, asymmetric encryption is used to encrypt symmetric keys. Then we use symmetric encryption. In fact, the security Interface Layer (SSL) is used to establish a secure conversation between the server and the browser.T
